Konica Minolta Bizhub C368 SMB Authentication Issue

Hello,


I am trying to print to a Konica Minolta Bizhub C368 that is shared over 
a Active Directory joined Windows Server with AD user authentication. I 
am able to successfully print a test page if I directly connect to the 
socket://<C368 IP address>:9100 with the following settings in the "User 
Authentication" tab:

User Authentication: 	MFP
Authentication Server: 	1
Username: 	Custom
Name: 	Public
Password: 	None

However, if I update the URL to 
`smb://DOMAIN%5CUSER:Pa%24%24w0rd@printserver/C368`, I am not able to print.

/etc/cups/printers.conf

Following status is shown:

ID	Name	User	Size	Pages	State	Control
C368-201    	Unknown  	Withheld  	179k  	Unknown  	held since
Tue 12 Mar 2024 02:19:52 PM JST  	Held for authentication.

then the job disappears as if it printed successfully.

Why is the status "Held for authentication"? I have already entered the 
credentials in the URL and the "User Authentication" tab. Any guidance 
on how to solve this issue is welcome. Thank you.
